Description

Paint finishing

Technical field

The utility model relates to paint finishing, more particularly, relates to the spray booth and the robot of paint finishing.

Background technology

Fig. 1 shows existing paint finishing.As shown in Figure 1, paint finishing 1 comprises spray robot 10,11 and the spray booth 12 that is fixed in ground.Camber line 13,14 is represented the movement locus envelope of spray robot 10,11 respectively.When passing through spray booth, target object 15 is sprayed such as the same target object 15 of vehicle body.

In existing paint finishing, because the movement locus envelope of spray robot is restricted, so robot can't finish the spraying work of whole vehicle body.Fig. 2 illustrates existing spraying area.As shown in Figure 2, on the end face of target object 15, spray robot 10,11 sprays out spraying path 20,21 respectively.There is patch 22 (in the dotted line) in spraying path 20,21, i.e. the zone of being repeated to spray by spray robot 10,11, this reduces coating quality.In addition, because existing paint finishing needs bigger space, so it is higher to invest the energy consumption of ventilating system of higher and spray booth.

The utility model content

At above-mentioned technical problem, the utility model is provided for coating is sprayed to the paint finishing of object, comprising: spray booth and at least one spray robot, described spray robot is fixed on the sidewall of described spray booth.

By spray robot being fixed on the sidewall of spray booth, for target object, it is big that its movement locus envelope becomes, and can cover the whole zone that will spray thus and reduce even eliminate patch.In addition, because spray robot is fixed on the sidewall of spray booth, reduce in its shared on the ground space, this for target object abdicated the space make its can be in the horizontal direction more near spray robot, so the compact more energy consumption that has reduced the space of paint finishing and reduced ventilating system of paint finishing of the present utility model.
